Great filter
Like the previous review, I too purchased this filter to have as a back-up and to swap during cleaning. The sheer size and 360 degree filter element design improves air flow, thus performance. Since I installed the FIPK on my Ford Ranger in 2005, I have noticed much improvement in mileage, power and engine response. The loud and noticeable "hiss" while air is drawn in is normal, and an indication of how much volume of air is drawn. I would also recommend cleaning long before 50,000 miles, perhaps no longer than 15,000 when the fuel filter needs changed. Be sure you know the proper inlet size and filter dimensions before ordering to ensure fitment and clearance. This filter is a K&N factory replacement part for my FIPK system, and perhaps others as well. Very good build quality, strong, and easy to clean per instructions.

Noticeable difference
I have not yet received this replacement air filter, but I already have this K&N kit installed on my 2003 Dodge Dakota sport and I can attest to the fact that the sound and horsepower difference are quite noticeable. I ordered the replacement air filter so I can have a spare to swap out when I clean it. That is probably the only disadvantage to the K&N system is that you have to wash the filter and wait for it to air dry before re-installing it. Getting a spare filter rectifies that problem.

it says it fits, it doesnt. It looks like it, but its doesnt!
If only it fit. Im replacing a filter for my Nismo intake. Universal 3inch. I followed the "check your vehicle " fitment on their website, did google search. Ok. It still doesnt not fit, it looks like it fits, but it wont clamp on. The damn oil from the filter is preventing a proper clamp, also it wont fit internally it bottle necks ever so slightly. Maybe i got a dud, but it was a easy return. I decided to buy DryFlow instead. That worked out for the better!
